r In Germany March 11, 1933 Claims.

My invention relates to devices for hauling upships onto dry land for repairs, etc., and afterwards returning them to the water.

The principal object of the present invention 5 is to so design such a device that for the tracks or rails upon which the ship-supporting cradle moves no inclined foundation is required below the level of the water, or upon the bottom, thus preventing the tracks from being choked up by dirt or sand. The improved structure forming the subject-matter of this invention is so designed that the rails, or the track respectively, can be easily surveyed and controlled, and if a repair or any alteration becomes necessary, for instance by reason of the ground sinking or settling, that such repair can be effected far more easily and conveniently than heretofore.

According to the present invention, the hauling device is suspended from rolls or wheels running upon rails or tracks located above the water on a suitable supporting structure.

The invention is illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 is a side-view of the device designed according to this invention, Figure 2 a plan thereof, Figure 3 a view of the lower end, and Figure 4 a View of the upper end.

On the drawing, a denotes the rails, 19 the suspended cradle, and c are longitudinal girders consisting, for instance, of reinforced concrete and resting upon piles d rammed into the ground. The frame of the cradle consists of a plurality of U-shaped suspended frames, each of which is formed by two lateral vertical members j and a horizontal bottom member e. The upper ends of the members 1 have bracket-like horizontal extensions 71 which extend over the rails a and to which extensions are secured the holders of rolls 9 adapted to run upon the rails. The lateral members 1 of the individual frames constituting together the main frame of the cradle are uniformly progressively reduced in length in the direction from the upper end of the structure to the lower end of the same, as shown in Fig. 1, said reductions corresponding, of course, to the degree of inclination of the structure.

In this way foundations in the ground, below the water, and dredging the bottom for the reception of such foundations, can be entirely dispensed with. Disturbing irregularities of the bottom along that stretch where the cradle is moved must, of course, be removed. Choking up of the track by dirt or sand need no more be feared, and if any of the piles should sink or settle, that will very soon be perceived and the length of rail affected thereby can be quickly and conveniently re-positioned by means of liners;

only if a pile should sink considerably it must be removed and replaced by a suitable longer one.

It is a matter of course that girders of any other suitable material than concrete, for in-' stance of steel, may be used.

Drawing of the cradle upwardlyalong the rails a is eifected by means of a suitable motor m operating winches w which are connected to the cradle by cables 70.

I claim:

1. A device for hauling up ships etc., comprising an inclined track-way disposed above the water, means for supporting said track-way, rolling elements adapted to move along said track-way, and a vessel-receiving frame suspended from said rolling elements.

2. A device for hauling up ships etc., comprising an inclined elevated track-way, piles supporting same above the water, rollers adapted to move along said track-way, holders for said rollers, and a vessel-receiving frame suspended from said holders.

3. A device for hauling up ships etc., comprising an inclined track-way, means for supporting same above the water, rails laid on said track-way, wheels adapted to move along said rails, holders for said wheels, and a vessel-receiving cradle suspended from said holders.

4. A device for hauling up ships etc. comprising an inclined track-way disposed above the water, means for supporting said track-way, rails laid on said track-way, rolling elements adapted to move along said rails, and a vesselreceiving cradle suspended from said rolling elements and comprising a plurality of successively arranged vertical U-shaped frames decreasing in length from their upper toward their lower ends and horizontal extensions projecting from the upper ends of said frames across said rails and carrying said rolling elements.

5. A device for hauling up ships, etc., comprising an elevated track disposed in its entire length above the water, piles supporting said track, a Vessel-receiving cradle comprising a plurality of successively arranged vertical U-shaped frames increasing in length from the lower to the upper end of the cradle, extensions outwardly projecting from the upper ends of said frames across said track and rolling elements adapted to move along rails on said track and carried by said extensions, the said frames being sus pended from said rolling elements.
